A simple computer based system to analyze Morris water maze trials on-line

Area of Science:

• Neuroscience
• Behavioral Science
• Scientific Instrumentation

Background:

• The water-maze is a common behavioral paradigm for studying learning and memory in rodents.
• Acquiring and analyzing data from such tasks can be complex and time-consuming.
• Existing systems may require specialized programming skills, limiting accessibility for researchers.

Purpose of the Study:

• To develop an integrated system for data acquisition, analysis, and storage for water-maze experiments.
• To create a user-friendly software application accessible to scientists without formal computer programming training.
• To leverage object-oriented programming and graphical user interfaces for flexible experimental design.

Main Methods:

• Development of a software application using LabVIEW (Laboratory Virtual Instrument Engineering Workbench).
• Integration of an IBM-compatible AT 486 computer and a video capture board for data acquisition.
• Incorporation of image analysis software tools (Concept V.i) for automated data processing.
• Utilization of a graphical user interface (virtual instrument) for interactive control and adaptation.

Main Results:

• A functional system for automated data acquisition and analysis in water-maze tasks was successfully developed.
• The graphical, object-oriented approach simplified software development and adaptation for specific experimental needs.
• The system provided scientists with an accessible tool for behavioral data analysis, reducing reliance on expert programmers.
• The integrated system has been in successful use for over two years in the researchers' laboratory.

Conclusions:

• The developed system offers an efficient and accessible solution for behavioral data analysis in rodent studies.
• LabVIEW's graphical programming environment facilitates the creation of adaptable scientific software.
• This approach empowers researchers to customize data acquisition and analysis for diverse experimental paradigms.
• The system enhances the reproducibility and efficiency of behavioral neuroscience research.
